ALEXANDRIA, Va. (WUSA9) -- An Alexandria deputy sheriff was arrested on Tuesday evening for sexually assaulting an inmate at the William G. Truesdale Adult Detention Center early Tuesday morning.

Fifty-two-year-old Bryant Pegues was arrested and charged with Rape and Carnal Knowledge of an Inmate' officials said.

The victim, an adult female, reported the incident to another deputy regarding the sexual assault.

Officials said Pegues has been terminated from his appointment with the Sheriff's Office. "We are entrusted with the lives and safety of those in our custody. The criminal actions of Bryant Pegues are a grave violation of the public trust. We will continue to assist Alexandria police and the Commonwealth's Attorney as they pursue a successful prosecution," said Sheriff Dana Lawhorne.

On June 5, Sheriff Dana Lawhorne released the following statement:

"I want to advise you of new developments in the case of former deputy Bryant Pegues who was arrested last week for sexually assaulting an inmate. Today, the rape charge (18.2-61) against him was nolle prossed and I agree with the decision of the Commonwealth's Attorney to drop this charge. The fact remains that he betrayed his duty to this Office and violated the public trust. The Commonwealth will continue its prosecution of him on the charge of Carnal Knowledge of an Inmate (18.2-64.2) and his preliminary hearing is scheduled for July 9."

Bryant Pegues was terminated by the Sheriff's Office on May 27. The dropping of the rape charge does not change his termination from this Office."

Additionally, I have arranged for an outside agency to review this incident with regard to our policies, practices, training and procedures. This review will be conducted by highly experienced command staff from the Arlington Sheriff's Office and will begin after the criminal case has been adjudicated."
